VVALVE FOR BASINS, TANKS, OR TUBS.

SPECIFICATION forming` part of Letters Patent No. 439,456, dated October 28, 1890.

Application filed January 3l, 1890. Serial No. 338,809. (No model.)

To all whom it may concern:

Be it known that I, PETER WHITE, of St. Louis, Missouri, have made a new and useful Improvement in Basin, Sink, and Bath-Tub Waste-Valves, of which the followingis a full, clear, and exact description.

The improvement relates mainly to those constructions which combine the functions of an overflow-pipe and awaste-valve; but it may be applied to a Waste-valve only.

It consists, principally, in the means Whereby the waste-valve portion o f the construction is readily operated, substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this specification, in which- Figure l is a vertical section of a basin having the improved valve; Fig. 2, a vertical section on the line 2 3 of Fig. l, the valve being closed; Fig. 3, a similar section, the valve being opened 5 Fig. 4, a vertical section, partly in elevation, showing the improved valve applied to a bath-tub and as when upon the outside of the bath-tub; Fig. 5, an elevation, partly in section, showing a modified bath-tub construction; and Fig. 6, a vertical section on the line 6 6 of Fig. 5, the improved valve being applied to the inside of the bath-tub.

The same letters of reference denote the same parts.

In Figs. l, 2, and 3, A represents an ordinary basin, and B represents the improved valve. The valve is constructed in any of the various forms ordinarily in use, and is modified only by the improved feature under consideration-@that is to say, its stem b is tubular, extending upward to a suitable level for the purposes of an overflow-tube, and having openings h for the escape of the Water into the stem, thence to iioW into the customary discharge-pipe C. The tubular stem b seats at b2, At a level above its lower end the stem is provided with a downwardlyA pointing scalloped shoulder b3. This shoulder is designed to coact with an upwardlypointing edge d of corresponding shape of an open-work tube or cage D, which surrounds the valve-seat Iii-that is, the shoulder b3 and the edge d iits the indentations d of the edge receiving the points b4 of the shoulder and the points d2 of the edge entering into the indentations b of the shoulder, and the c011- struction is such that when the stem is seated the shoulder and edge fit, as described andf as shown in Ffr. 1; but by simply turning the stem b partially around until the points of the two parts b3 CZ are in opposition, as in Figs. 2 and 3, the stem is unseated and upheld, and the water from the basin can waste through the openings d3 of the cage int-o the discharge-pipe C.

The operation is not only readily performed but provision, by means of the bars d* of the cage, is made by which particles too large for the discharge-pipe are kept from passing thereto. The rotary motion of the stem in seating and unseating it is also favorable for keeping the stem clear of dirt.

In the construction shown the parts b3 d each have two point-s, and byturning the stem half-Way around the valve is unseated.

So far as the remaining features of the construction are concerned, they can be varied indefinitely without departing from the principle of the improvement.

In Fig. a the valve is shown inclosed, saving the top of the stem in a chamber E, which is without the tub F, but in communication with the discharge-pipe C, leading from the tub.

In Figs. 5 and 6 the valve is shown within the tub F; but as no means are employed at the upper end of the valve-stem to confine it vertically in position a thimble G is employed therefor, the thimble being screwed onto the cage D, as shown. The cage in all cases is suitably confined to the bottom of the basin, sink, or tub, substantially as shown.

I desire not to be limited to any particular shape of scallop or indented edge in forming the parts ha dso long as the valve in unseating it is raised, so that the points of its shoulder ride upon the points of the edge d.

The cam-shoulder b4 d2 are rounded at 95 their points, so that when the valve is turned up it will stand up indefinitely, which would not be possible Wit-h a single slant nor with cam-shoulders having acute points.

I claim- IOO The combination of Iche valve-seat, the valve which can be turned both Ways, and the valve-stem provided with Jche downwardlypointing scalloped shoulders and the Wateropenings, with the cage having the upwardlypointing soailopededge, said valve-seat being below vsaid interacting edges and Within said cage, and the scallops of the interacting edges having a double bevel, substantially as described. 1o
